Corrosion

Make corrosion crumble

Corrosion is a gradual chemical or electrochemical attack of a metal or alloy by agents in the surrounding atmosphere. The resulting reaction causes disintegration of surfaces and material loss that can take many forms.

• Aqueous corrosion: destructive service chemistries such as sulfuric, hydrochloric, nitric and hydrofluoric acids cause damage to the metal substrate

• Cavitation corrosion: the collapse of air bubbles or gas pockets removes the protective film on a metal or alloy

• Chemical attack corrosion: substrate dissolves due to very low or very high pH in the environment

• Cyclic corrosion: metal surfaces are wet with corrosive fluids, then dried and re-wet, creating a very high concentration of ions and an extremely corrosive solution

• Fretting corrosion: hard surfaces rub against each other in a corrosive environment

• Galvanic corrosion: two dissimilar materials are brought into contact in a corrosive electrolyte, or an electrical current is passed between metals joined under water

• Hot corrosion: metal surfaces are exposed to gases containing chloride or sulfur compounds at very high temperatures (1100° to 1700°F / 593° to 927°C)

• Uniform corrosion: a chemical reaction with the environment that causes a general corrosive attack over the entire surface of the component 

Coatings are one of the most powerful tools available for protecting components in corrosive operating environments. We offer an unmatched variety of coatings and treatments to protect your parts.

We’ll work with you to evaluate your part's function, dimensions, weight, alloy and temperature exposure to select or develop the coating that addresses your corrosion prevention needs.
